Roller Shutters – Part 4

Roller shutters refer to doors constructed from various slat material rolled up in a roll above the door opening. For ease of operation the doors are balanced by means of torsion springs

Roller shutters are a type of door or window shutter consisting of many horizontal slats (or sometimes bars or web systems) hinged together. The door is raised to open it and lowered to close it. On large doors, the action may be motorized. It provides protection against wind and rain. In shutter form, it is used in front of a window and protects the window from vandalism and burglary attempts.


Roller shutters have many applications, including doors for vans, garages, kitchens, schools, prisons and warehouses. In some parts of the world, roller shutters are subsidized by local governments [1] due to the inherent security benefits. In areas that are frequently exposed to inclement weather, roller shutters are used as a method of insulation and can protect windows against hail damage.
